FIX: A suspended orchestration instance is not resumed immediately in BizTalk Server 2006 if the orchestration contains a Delay shape

Consider the following scenario:

• In Microsoft BizTalk Server 2006, you have a BizTalk orchestration that contains a Delay shape.
• You restart the BizTalk host instance, and then you immediately restart the orchestration.
• You enable the corresponding receive location.
• You start the orchestration's corresponding send port.
• You drop a message to the receive location of the orchestration.
• The output file is displayed, and the orchestration instance is suspended.
• You try to resume the suspended orchestration instance

In this scenario, the resume attempt fails immediately, and the orchestration instance enters a dehydrated state. The orchestration instance is not resumed until the delay timer has expired.

When you try to resume an orchestration instance, a restart message is inserted into that instance. However, BizTalk Server does not do this if the orchestration instance has messages in the queue. In the scenario that is described in the "Symptoms" section, the existing messages in the queue are timer messages that will be delivered in the future. Therefore, when you try to resume a suspended orchestration instance, the instance is not resumed immediately.

Note This hotfix inserts the restart message in the suspended queue when the instance is in a suspended state. When the instance that is in the suspended state is resumed, the messages that belong to this instance are moved from the suspended queue to the application queue. Additionally, the orchestration instance is started.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
